From what I’ve read, you’d need a pretty big spaceship in order to rotate it fast enough to generate artificial gravity.
“From what Ive read, youd need a pretty big spaceship in order to rotate it fast enough to generate artificial gravity.”
Size matters.
1km circumference.
A configuration with a radius of 225 meters and a rotation of 2 RPMs will give you 1 earth gravity.
I think this scale of structure is do-able, maybe a bit of a stretch goal. Certainly a fraction of this is within current reach, when one looks at the 100m truss length of the ISS.
However, from what I can see, the biggest pain in the rear is where the spinning section meets the stationary central core. How do you do power hookup? Mechanical hookup that is robust and can take a torque? Not to mention if the stationary central core is habitable or needs service, how do the astronauts move between sections?
(Perhaps having the entire structure rotate is the solution for a robust craft that we can implement now.)
